!!!!! I am sorry for my slowness, but. . . the VW help reads
"The Cut 3D Section command cuts a 3D section, or slice, through a 3D model while leaving the model intact. The slice is placed on a new design layer."
This is exactly what I want - I want to add line work to the section in a design layer - but:
1. I can not find the "cut 3d (2d) section" I can find the "view/create section viewport" is this the same thing? but where is the 2d. . .
2. When I use the "create section viewport" it puts the slice on a sheet layer - that I can choose - but not on a design layer as described above (from the VW help)
